Viterbi Decoder 7.0 Issue: No Output SysGen

Jump to solution

Hi,

 

I'm having a hard time with the Viterbi Decoder 7.0 Block. No matter what configuration parameters i set, the outputs are allways NaN.

 

A hard test would be to configure it in Serial mode, set some 3b data at data_in0 and data_in1 ports and push nd input to '1' for a clock cycle. RFD output should be '0' at this time and '1' before, according to page 26 of the block datasheet. But it is allways NaN! Please see my WaveScope in attach.

 

I have the System Generator License (not specific to any block though), however i have been able to use other green blocks such as the DeInterleaver.

 

What can i possibly be missing?

 

 

Best,

JM

You will need a license for the Viterbi Decoder, which is separate from the license for SysGen.

You can install license with ISE . Sysgen will detect license for license manager
